Post JT Excellerator 4.0 review

This review was donr by pbstar.com which is owned by paintballgear.com so they know what they're talking about.
FireIce -> you might want to add this to a stickey/permanent thread at the top of the forum.

Features
JT has entered the gun market with its Excellerator line of paintball guns. We chose to review JT's fully upgraded Excellerator 4.0 for this review, but keep in mind that the lower model versions are virtually the same gun minus a few upgrades. The 4.0 comes with a vertical feed, expansion chamber, double finger trigger grip frame, JT barrel, rear cocking bolt, low pressure chamber and a drop forward with regulator and micro-gauge.

Impressions
We were very impressed with the all-metal design of the Excellerator. JT has always produced quality products, but with Brass Eagle's acquisition of JT, many people have feared a decline in product quality. We are happy to say this isn't so with the Excellerator. It is a very solid (perhaps a little too solid!) gun. Moving onto the bolt, we quickly found something that we weren't so thrilled about. The bolt is removed by pulling a retaining pin out of the side of the gun, but this pin does not incorporate a ball bearing to hold it in place like some other guns have. Instead, the pin is held in place by a key ring that must be painstakingly removed each time the bolt is removed. This really isn't something that we like to see in a paintball gun. Aside from the fact that it would be all too easy to misplace the key ring, most paintball players won't want to be bothered with un-threading a key ring every time they want to remove the bolt. Ever try doing something like that when your hands are dirty and greasy, or even worse, frozen from the cold? We were so distressed about this tiny little thing that we called up JT to see if they were changing this design in the future, and they told us they were. Perhaps we over reacted, but it's the little things that count.

Appearance
It is hard not to be impressed when looking at the Excellerator 4.0. It has a very Spartan look to it. The gun body and grip frame are anodized black and everything else on the gun is done up in silver. A great combination of colors. But that isn't what makes this gun look so good. Here and there a few stylish touches add to the overall appearance of the Excellerator. Each side of the gun body has some light milling; much like what Bad Boyz Toyz does with its Autocockers. On the left side of the gun body is a black and silver JT logo and the grip panels themselves have the JT logo etched into them. Moving on towards the front of the gun, the barrel is one of the best looking barrels we've seen since the Dye Boomstick (it borrows a little from the boomstick design).

Balance
The Excellerator 4.0 is just under 18 inches in length, with the barrel taking up 9.5 inches of that 18. Since it is such a small gun you wouldn't imagine it was so heavy. We are proud to announce that this gun has received the paintballstar.com reward for the heaviest mid-range semi in town. Perhaps we are exaggerating too much, The Excellerator 4.0 probably weighs in the neighborhood of 3-3.5lbs, but it can get a little heavy when you add on a hopper full of paint and a C02 tank. Fortunately, the mass of the Excellerator is actually balanced pretty well. The gun body and grip frame are very solid, but this actually helps make the Excellerator balance nicely. The vertical feed keeps the hopper centered over the gun, and the drop forward positions the tank in a comfortable position (although we'd like to see the drop forward drop a little more "forward"). All of this is added to by the large and comfortable expansion chamber, whose design is actually quite ingenious.

Performance
We played a lot of paintball games with the Excellerator 4.0 before putting our stamp of approval on it, and one thing we found out was that this gun performs very well on C02. This is most likely due to the regulator and expansion chamber. The regulator prevents the gun from spiking by supplying a constant pressure to the Excellerator while the expansion chamber filters out liquid C02 before it can be drawn into the valve chamber. Most expansion chambers do a decent job of preventing liquid C02 from overwhelming the gun, but the Excellerator's expansion chamber virtually eliminates liquid C02 as a problem. It's design is similar to that of an anti-siphon tank. C02 enters the expansion chamber and is collected at the bottom. The only way for it to actually enter the gun is through the small tube that you see in the picture on the right. With the liquid pooling at the bottom of the expansion chamber (gravity is great), the gaseous C02 is free to travel up into the tube and on to the valve chamber. What this means for the user is that their gun will perform more reliably and efficiently in cold and hot climates. To demonstrate this point, we fed the Excellerator's requlator liquid C02 and dry fired over 500 shots (it was hard to keep an exact count when firing that fast, but we estimate that it was AT LEAST 500). The regulator and expansion chamber got a little cold, but they did not ice up like we expected. In fact, we fired this gun so fast and for so long that a cloud of white fog was formed around the gun. Eventually, the barrel became covered in a thin layer of ice and was ice cold to the touch. But still, the regulator and expansion chamber did not ice up. Very impressive! For those interested in using the Excellerator on N2 there is no need to worry; the expansion chamber will not affect performance.

Accuracy
To test the accuracy of the Excellerator, we mounted it securely into a vice and fired 30 paintballs at two targets 25 and 40 yards away. For these tests we used a VL 12volt Revolution hopper filled with Diablo Inferno paintballs, a 20oz C02 tank, and an 88ci Air America Melee tank. While we performed the accuracy tests, we also recorded the velocity of each shot fired at the targets via a hand held chronograph.

Close Range w/C02
We pointed the Excellerator at the target 25 yards out and fired 30 paintballs. Five shots missed the target, and the remaining 25 shots impacted in a very tight grouping shown on the right. This barrel performed much better than we expected it to at close range. In fact, the Excellerator with JT barrel yielded more accurate results at 25 yards than some guns costing 2-3 times the amount of the Excellerator!


Not only does this barrel look fantasic, but it also performs great at close range

Long Range w/C02
Next, the Excellerator was adjusted and pointed at the target stationed 40 yards away. Seven shots missed the target this time, with the remaining 23 shots spreading out over most of the bottom half of the target. These results, are closer to what we would expect from a gun in the Excellerator's price range. While the Excellerator performs great at close range, it's clear that the 9.5" JT barrel isn't better than select aftermarket barrels for long range.

Close Range w/N2
Accuracy at close range with an Air America Melee system did not show an improvement. Four shots out of 30 fired, and the remaining 26 hit the target in a very similar shot grouping to our close range with C02 accuracy test. We can see from the picture on the right that the shot grouping is actually a little tighter with the Melee than with C02, but with 4 shots missing the target, the results can be said to be virtually similar.



Long Range w/N2
At long range, we saw a definite improvement in accuracy while using the Air America Melee system. The shot grouping is just as spread out as our C02 shot grouping was, but you can see from the picture that the area in the middle of the target had a higher concentration of impacts. In all, only 5 shots missed the target (compared to 7 with C02).

C02 Consistency
As we mentioned in the previous section, we recorded the velocity of each shot fired during the accuracy testing. Since the Excellerator comes with a regulator it should be of no surprise that it is going to perform consistently with C02. The shot to shot variation in velocity(standard deviation) for the first 30 shots fired at the 25 yard target was 4.33fps, with the average velocity for these 30 shots being 285fps. A standard deviation of 3fps is the best we have ever seen while performing these reviews (it was with an Automag powered by an Air America Raptor).
At long range, the results were very similar. The average velocity dropped slightly to 281fps, and the shot to shot variation in velocity remained about the same at 4.39 fps. A standard deviation this small means that your accuracy will increase, which is part of the reason why we found the Excellerator to be so accurate (another factor to consider is the high quality JT barrel).

JT Excellerator 4.0 review continued


N2 Consistency
Using a nitrogen system did not show any improvement in consistency. The average velocity of the first 30 shots fired was 280fps and the shot to shot variation in velocity for these 30 shots was 5.56 fps. We identified one shot in particular that "threw off" the standard deviation result in the first string of 30 shots. You can see from the chart that shot number 10 in the close range series was significantly higher than the rest at 294fps. If this one value is removed, the standard deviation comes out to be just under 5fps.
The next 30 shots fired had an average velocity of 279fps. Here we did see an improvement in using the Melee vs. a C02 tank. A nitrogen system keeps the supply of air pressure at a constant, meaning you won't have to worry about your velocity increasing or decreasing throughout the day. The shot to shot variation in velocity for these 30 shots decreased to 4.28 fps. From these results we can assume that the shot to shot variation in velocity with the Excellerator should be the same no matter which gas you use. This doesn't mean that Nitrogen shouldn't be considered a future upgrade for the Excellerator because it does provide much more than just increased accuracy and consistency to your gun. But it does mean that you won't have to worry about having a less-accurate gun on account of not being able to afford an N2 system.


Front Players
The Excellerator 4.0 has a small barrel, vertical feed, drop forward and an expansion chamber. Most front players these days are trying to make their gun as small as possible. With the Excellerator, there isn't anything else you need to buy or add on to make it a better front player's gun. As our accuracy testing revealed, the JT barrel is super accurate at close range, which is perfect since front players don't need to shoot the entire distance of the field. The only thing we can possibly say is lacking on the Excellerator is a super fast trigger that today's front player has come to demand from their paintball gun. It is not that the Excellerator isn't capable of high rates of fire, but the trigger pull is a little on the long side. This makes it harder to shoot short, fast bursts while snap shooting.

Back Players
Players who like to sit back and shoot it out with their opponents will be happy to note that shooting a long string of paintballs is very easy to do without skipping a shot. We noticed that most players we let use the Excellerator could fire for a long period of time with relative ease, but they had a little more trouble while attempting to limit themselves to a couple short, fast bursts. The vertical feed hopper on the Excellerator is a big plus for back players since it allows for a more consistent feed rate with less skipped shots than your standard right hand feed or powerfeed. In the case of a ball break, a complete cleaning of the Excellerator's bolt is impossible while on the field. Sure you can take the time to remove the bolt, but you'll have no way to put it back in once it is removed without the use of tools. We only broke one ball while using this gun, however, and the JT barrel seemed to shoot through that ball break quite nicely. We never even noticed it broke a ball until we came back to the staging area after the game was over. Back players looking for an accurate gun will be pleased with the Excellerator 4.0s performance, but they still might want to consider an upgraded barrel in the future. This is just a theory at this time, but it could be that short barrels(like the Excellerator's JT barrel), while very accurate at close range, degrade in accuracy faster than a longer barrel. Stay tuned for more tests on this subject.


UpKeep
Upkeep with the Excellerator 4.0 is very simple. Add 3 drops of paintball gun oil into the ASA (air source adapter), screw in your C02 or HPA tank, make sure the barrel is removed and fire about 30 shots to cycle this oil throughout the gun. Other than that we suggest removing the bolt and striker after each use, cleaning them off and rubbing one or two drops of oil on their orings. We suggest this in addition to the previous method of cycling oil through the gun because the bolt is partially exposed during play. This makes it easier for dirt and other contaminents to get inside. Having a well lubricated gun can make the difference between a working gun and a non-working gun if this happens to you in the middle of a game. We never experienced this problem (or any others for that matter) while using the Excellerator, but it is better to be safe than sorry.
This picture on the left shows the low pressure chamber, valve spring, and valve stem. What is interesting about this spring is the fact that the valve spring is not like your typical valve spring. It is wider at the base which is supposed to allow for a more reliable operation.

Conclusions
On the whole, we were very impressed with the quality of the Excellerator. Despite the fact that it is a little on the heavy side the Excellerator handles very well. The trigger isn't as short as we would have liked, and the "field strip" system is lacking. Other than that, we think the Excellerator 4.0 is one of the better guns on the market. The barrel is accurate, and the expansion chamber and regulator make a great combination for C02 use. Players looking for a gun that they can upgrade won't want to consider the Excellerator 4.0 since it has just about everything you need in a paintball gun, including the much coveted vertical feed. All of these features do not come cheaply, however. The Excellerator is a little more expensive than some other fully upgraded guns in its class, but its high quality parts and solid construction justifies its cost for most players.

pbstar did a good review of the 4.0. The only thing I don't agree with is that it is on the expensive side. You can get the 4.0 for as little as $160. This is way cheaper and lot higher quality than the Spyder Shuttle (shutter?), which is going for about $200+.

Check out pbreview.com. There are lots of reviews (78) from owners there. 9.7 out 10 was the rating for the 4.0. Not bad for JT's first marker. What really makes me feel warm all over is that some of the owners were Spyder (Kingman) owners and prefer the JT.

Man my excelleratior has given me nothing but trouble. First i was playing and the bolt shot out the back of the gun and hit me in the eye, now im gonna have to go buy a mask cuz of the bolt. When i screwed in my 35 ounce c02 tank the barrel shot off and impaled someone, and nearly look out the nitrogen fill station. The expansion chamber shot out and dug itself about 4 feet into the granite bedrock i play on. It rocketed the gun about 16 feet into the air and ASA broke off and it shot the 35 ounce c02 tank into my face and knocked me unconcious a day and a half. When i woke up the proshop was burnt to the ground and there were a few dead bodies laying around, i was also missing my pants.


:edit: Since the event the devil has talked to me and specified my gun holds the key to the end of the world.
